[ML] Enable all ES side ML features for the ES3 project type (elastic…

…#168646)

The aim here is to enable the Elasticsearch APIs for all ML features in
the ES3 serverless project type, while still leaving the UI support for
anomaly detection and data frame analytics unavailable in this project
type.

Therefore, the only changes in this PR are to the ES config options
supplied during tests.

If we ever want to enable the UI support for anomaly detection and data
frame analytics in the ES3 project type then a followup PR will be
needed.
